V V 2 Claims. (Cl. 81g71) V My invention relates to a wrench, and more "videdflwith an integral v shaped'portion includparticularly to a wrench adapted for use in reing anangularly disposed portion or leg 6 joined moving the screw threaded plugs .from steel to .one end .of the shankl5. Formed integral with drums in which various materials such as oil, and extending outwardly? from one surface of the naphtha and the like are shipped to the user. angularly disposed leg 6 is a working section in Steel drums of this type are provided with difthe form of a square stud or boss 1 adapted to ferent types and sizes of screw plugs owing to fit into a screw plug which is provided with a the fact that the various manufacturers of the Square recess or depression.

It will be seen, there- With the Shank Portion 5 is g d as Shown fore, that in the past it has been necessary for i Figure 1, and Such enlarged portion l3 the users of the materials shipped in steel drums 15 ovlded with a centrally disposed Square pe of this e to have on hand a plurality of difi ing M. This square opening I4 is adapted to fit 35 m; types of Wrenches f r removing the Various over the square projection which is provided on kinds of screw plugs from the drums, as well as some Plugs- Suitable tools for removing or breaking the seals The angularly dls posed portlon outwardly over the plugs, which, of course, is disadvanof the enlarged Portlon Provided With a Pa 40 tageous of spaced apart oblong projections or studs I5 40 with this situation in View my present inven and I6 positioned in longitudinal alinement with tion has for its principal Object to provide a each other.

This portion l'l may also be used as a screw driver.

Formed integrally with and extending outwardly from one side of the enlarged portion 13 is a pair of spaced gripping jaws l9 forming a recess 20 that is adapted to receive the centrally disposed projection or bar provided on some screw plugs.

It will be seen from the above that a mechanic equipped with this wrench can easily and quickly pry out or break the seal and remove any one of the various kinds of screw plugs that are commonly used on steel drums, thereby saving the time that might otherwise be required for finding a wrench to fit a particular type of plug, as well as finding a suitable tool to remove or break the seal, so that the necessity of keeping on hand a plurality of wrenches is avoided.

I claim:

1. An article of manufacture comprising a tool having a shank formed of a flat elongated strip carrying a generally V-shaped portion one leg of which is joined to said shank at one end, and a pair of difierently formed polygonal socket having a shank formed of a fiat elongated strip carrying a generally V-shaped portion one leg of which is joined to said shank, a pair of differently formed polygonal socket engaging bosses,

' one on the outer side of each leg of said V-shaped portion, and a reenforcing web joining the sections of the legs of said V-shaped portion carrying said bosses and disposed in a plane extending longitudinally of the shank and intersecting both of said bosses, said V-shaped portion being joined to the shank so that each leg is disposed substantially at the same oblique angle with respect to the shank, whereby the shank can serve as a handle in substantially the same relation for either boss.
